TRUCK.

SPECIFICATION forming part of Letters Patent N o. 72? 618, dated" May12, hiApplication filed m 9,1902. Seri l No. 106,652. (No model.)

T0 at whom it may concern;

Be it known that I, JOHN M. HANSEN, a resident of Pittsburg, in thecounty of Allegheny.

and State of Pennsylvania, have invented'a new and useful ImprovementinTrucks; and

I do hereby declare the followingtobe a full, clear, and exactdescription thereof.

My invention relates to trucks for railwaycars, and more especially totrucks of the diamond-frame type.

The object of my invention is to improve trucks of this character indetails of construction,which are hereinafter fully described andclaimed.

In the accompanying drawings, Figure 1 is a plan View of myimprovedtruck. Fig. 2 is a side elevation thereof. Fig. 3 is a. transversevertical section of the same. "Fig. 4 is a transverse vertical sectionof one side frame on the line 4 4,Fig. 2; and Fig. 5 is a horizontalsection on' theline 5 5, Fig. 2.

My truck-frame comprises top and bottom arch-bars, tie-bars, columns,journal-boxes, and the like. The top arch-bar lis'of inverted-troughshape, having laterally-project; ing flanges 20f suitable width on itslower side. Thisiarch-bar may either have its ends open or else havethem closed or boxedin, as-

shown in Fig. 2. The lower arch-bar 3 preferably is of rectangularcross-section and in general may be of the shape usually employed formembers of this kind. The arch-bars are united by rivets 4 at theirouter en ds and diverge from each other toward their centers. Thetie-bars 4 may be of any-preferred form, preferably of rectangularcross-section, and,

are united to the lower arch-bars near their centers, while their endsare separated from the lower arch-bars to receive the journalboxes 6therebetween. may be of any suitable or preferred construction.

These journal-boxes- They are separated from the arch-bars by meansofthe liners 7, which lie between Between the top and bottom arch-bars,near their middle portions, are the columns 10, which are formed ofpressed steel plates, having their vertical portions trough-shaped, asshown, and provided with laterally-projecting fla'nges 11 on theirsides. The upper ends of these columns are suitably flanged, as shown at12, for riveting to the flanges of the top arch-bars. The lower ends ofthe columns are bent to form the flange 13, through which they aresecured to the lower arch-bar. Oolumn liners 14, formed of bent orpressed metal plates, are riveted to the inner faces of the columns andhave their bent ends lying, respectively, underneath'the top arch-barand above the lower arch-bar. These} liners are formed of quite wideplates and project inwardly a considerable'distance inside of the fromside frame to side frame, being'riveted tothe side frames and-lyingabovethe in- ;turned endsof the columns andliner plates.

This spring-plank supports the, usual sprin gs 17, upon which 'reststhetruck-bolster 18. This bolster may be of any preferred or desiredconstruction and is provided'with the chafing-castings 19, which bearagainst wearing-plates 20, formed of rectangular pieces of plate metalattached to the inner faces of the column-liners. Riveted to the lowerflanges of the topLarch-bar and lying between the inturned upper ends ofthe column-liners is a plate 21, which projects inwardly, as shown, andhas its inner end flanged to present a bearing-surface of proper size todistribute the side thrust, said plate being adapted to come in contactwith: the truck side bearing 22, attached to the bolster, and limit thesidewise movement of the bolster.

The truck will of course be provided with the usual brake mechanism;but, this forms no part of the present invention, and therefore will notbe described. The particular form of brake mechanism shown intheg'drawings is intended to be illustrative merely.

The truck side frame described is very simple and strong. All of theparts are so formed that the rivets pass through outwardly-projectingflanges or the like, so that hand-riveting is avoided, thus making iteasy and expeditious to assemble the same.

\Vhat I claim is- 1. In a car-truck, thecombination of side framescomposed of top and bottom arch-bars, two separate column-posts havingtheirends flanged and riveted to said top and bottom arch-bars, saidcolumn-posts having their vertical portions trough-shaped, a springplankoverlapping the lower flanges of the column-posts and secured to thebottom archbars and uniting the side frames, and a bolster having itsends projecting between the columns and underneath the top arch-bars.

2. In a car-truck side frame, the combination with top and bottomarch-bars, of two separate column-posts provided with flanges at theirupper and lower ends for riveting to the top and bottom arch-bars, saidcolumnposts having their vertical portions troughshaped and providedwith laterally-projecting flanges, and column-liners applied to theinside faces of said colu m n-posts and secured to the flanges thereof,said column-liners having their top and bottom ends bent inwardly andlying respectively below the top arch-bar and above the lower arch-bar.

In a car-truck side frame, the combina tion with a top arch-bar ofinverted-trough shape and provided with laterally-projecting flanges, ofa bottom arch-bar riveted to said top arch -bar near its ends anddiverging therefrom at its middle, and column-posts interposed betweensaid top and bottom archbars and having their ends flanged and rivetedthereto, said column-posts having their vertical portions trough-shapedand provided with laterally-projecting flanges.

4C. In a car-truck side frame, the combination with top and bottomarch-bars united near their extremities and diverging at their centers,of column-posts interposed between the diverging portions of saidarch-bars, column-liners applied to the inner faces of the columns andprojecting inwardly beyond the truck-frame, and brake-beamhanger-brackets riveted to said column-liners.

5. In a car-truck, the combination with a bolster provided with ashoulder, of a truck side frame comprising top and bottom archbars,column-posts interposed between said arch-bars, and a stop-plate securedto the top arch-bar between the column-posts and projecting inwardly andhaving its inner end lying in proximity to the shoulder on the bolster.

In testimony whereof I, the said JOHN 1V HANSEN, have hereunto set myhand.

JOHN M. HANSEN. IVitnesses:
